[Patch, AArch64] Add missing support for hexadecimal-format floating-point literal in the FMOV instruction

[Yufeng Zhang]

Hi,

The AArch64 floating-point move (immediate) instruction FMOV can have 
the floating point constant specified either in decimal notation or as a 
string beginning "0x" followed by the hexadecimal representation of its 
IEEE754 encoding.

This patch adds the missing support for the latter notation.

OK for the trunk and 2.23 release branch?

Thanks,
Yufeng
